' SPFCIFICATION forming part of nemers Patent No. 381,268, atea Aprn 17, ieee.y

Application filed November 12, 1887. Serial No.` 255.026. (No model.) l

yTo all whom izimay concern:

Be it known that I, FRANK B. Moons, of.

the cit'y, and county of San Francisco, State of California, have invented an Improvement in Sash-Holders; and I hereby declare the followling to be a full, clear, and exact description of the same.

My invention relates to devices which may be used to fasten windows and prevent vtheir bei-ng opened when in one position, and when reversed will act as a Catch to hold the sash at any point where it is desired to have it remain when raised; and my invention consistsin the sash-holder hereinafter fully described and specifically Claimed.

Referring to the accompanying drawings for a more complete explanation of my invention, Figurel is a view showing the device attached to a window-sashand used asa fastener. Fig. 2 shows it reversed so as to actas a catch to hold the window up'. Fig. 3 is avertical section-cfa window, showing theapplication of my device. Figi/.1. is a perspective view of my device, showing its application.`

A is'an arm having its center pivoted or fulcrumed upon aplate, B,-b'y means of a central screw or bolt, C. Upon the outer ends of vthis arm aretwo segments, .D D', the outer faces 'of which are curved and toothed or corrugated,

sothat they will bind against the sash or frame against which they are brought into Contact and act as a lock. The curve of these two segments is not formed from the center of Inotionfof the'arm, b'ut they are eccentric to the l center of motion, so as 'to insure their binding more strongly with any additionalv pressure" that may be brought upon them. These two y segments project farenough from the'plate on each side so that when either of them is turned to come in Contact with the window-sashthey will Apress against it, the plate B being secured to the casing by the side of` the'lower sash, as shown in Fig. 4. 1 L

Projecting from the arm A at a point midway between the two segments is a lever or Y handle, E, having a button, F, by which it is easily turned, so that either of the segments may be brought into Contact with thesash, as may be desired. In order to Vholdthese segments in place, I- havefltted a curved spring,

l ver attached to it,'bywhich it may be.` turned, Vand the spring and anti-frictional stud moving G, into the frame or CapH, which'isrsecured 'i l to theplate B and covers the moving parts, y,

and a roller, I, is fixed upon a stud projectingupwardly from thearm Aat Cneside of the .l

pivot or fulcrum, so that this rollertravels upon theinside ofthe curved spring, asshown in Fig. 1. When the deviceis'to be used as a fastener, the lever will be turned downward, as shown in Fig. 1,and thesegment Dl will be lbrought in contact with the/sash and'its cor? rugatededge will cause it to bind, so that any l attempt to raise the sash will be resisted, and

the sash thus locked in "place andv prevented g from rising.

If Vit is'desired to raiseY the sash andY retain? it at any particularpoint, the lever-arm vwill l up, andv when the weight of thesash presses downward the segment willbindto prevent it from moving. When this device is to be used i l75 l in't'heupper sash, it will preferably-loe set into thesash ,itself7 and the segment will then the casing. n Y Y KIt will be manifest that when fixed in "the sash, so as totraveLwith the sash,.the lock device is itself fastened to the casing.,v

Having thus described my invention, what I` claiml as new, and desire to secure yby Letters Patent, is' f* .travel againstthe,parting-strip sor the side of or holding segments will operate'inexactly'the i' i reverse `manner from their operation when the The reversible cenlrally-fulcrumedarm hav- Y ing the segments upon its' opposite ends, aleover the spring, so as to `hold the device in either. position, substantially as herein dep scribed.

In witness whereof I have hereunto hand.:y l g f y.
